Abstract

Une sonde rectale comprend un cathéter (1) doté d'un axe longitudinal autour duquel est monté un ballon souple, gonflable à faible pression (5), dont la paroi porte un capteur de température. Cette sonde comprend aussi un dispositif qui permet de la maintenir dans une position appropriée dans le rectum d'un patient, et un dispositif de gonflage du ballon lorsque ce dernier est en place, afin que le capteur de température soit en contact étroit avec le côté antérieur du rectum. On décrit aussi un procédé qui permet de contrôler la température de la muqueuse rectale d'un patient pendant qu'il subit un traitement thermique de la prostate.
